Cell type proportion inference. (A) Each point represents a single RNA sample, colored by the site:tissue and positioned according to its coordinates on the first two PC axes of the projections onto seven sets of cell-type-specific genes identified by Bezrutczyk et al. (2021)⁠ in maize leaves. (B) The highest point in each column shows the standard deviation of the cell-type projection scores within each tissue. Box plots show the distribution of 200 randomized projection scores based on random sets of genes. (C) Distributions of the PC1 coordinates for the MetLeafbase samples, separated by population and range of the field.
